FEEDING MECHANISM FOR QARDING-MAOHINESQ Specification of Letters Patent.

Patented Sept. 24, 1907.

Application filed August 22,1904. Serial No- 221,597.

To all whom it may concern:

Be it known that I, HARRY KEMP, a citizen of the United States, and a resident of Newton, in the county of Middlesex and State of Massachusetts, have invented new and useful Improvements in Feeding Mechanisms for Carding-Machines, of which the following is a specification.

I My invention relates to feeding mechanisms for carding machines and consists in improvements in the controlling mechanism of geared travelers, such as shown and described in the Letters Patent of the United States, No. 701,487, granted to me under date of June 13, 1902. In that patent, to which I have reference, the frame'marked A represents the ordinary bridge theretofore used in the construction of diagonal card feeds and the devices which embodied my aforesaid patented improvement were combined and designed for application to such existing frames or bridges, and while they were and are, entirely and satisfactorily operative, the forms necessary to adaptation to the existing frames, which had not been designed originally with a view to receiving such attachments as represented by said patented improvements, were not such as would commend them to the machine designer intending to build a complete feed, with a frame properly designed and adapted to receive my said improvements. In my said patent the relationship of rolls D and stop or abutment 29 is explained in such detail that repetition is unnecessary. The abutment 29 of said patent is shown as carried by a U-shaped or arched yoke 28 which extends over the' web of the bridge A, and is part of or rigidly secured to the plate 24 which carries the rolls D. This yoke permitted the 1 roll carrying plate to be attached to the frame A without any more special work than that involved in cutting the slot 26 to admit the clamping bolt 25.

In the drawings hereto annexed I have shown my improvement on the construction of the roll-carrying Figure l is an elevation of a feeding mechanism for carding machines embodying my improvements. Fig. 2 is a sectional plan of one end of the mechanism shown in Fig. 1 the upper portion thereof being broken away. Fig. 3 is a section on line 33 of Fig. 1. Fig. 4 is a modification hereinafter described.

Having reference to the draWings,A represents the bridge of my improved feed mechanism, and as in the patent above noted this bridge carries the guide rod B upon which is hung the carrier E, the latter being reciprocated by chain D so as to lay the sliver upon the aprons (not shown) as usual. The carrier E comprises the usual plate or rocker G carrying the feedrolls g and gears g, the latter alternately cooperating with rack K as in the mechanism of my said patent.

The sprockets D which support the belt or chain D are themselves supported by brackets H herein shown as fastened to the inner side of the bridge A by bolts h extending through longitudinal slots if provided in the web of bridge A, thus making provision for varying or adjusting the region of movement of the carrier with relation to the aprons (not shown):

My present improvement consists in making the bridge A with a second pair of slots h parallel with slots h and through which the abutments h project into the path of'the lug g on rocker G. That is, the abutments h are not only fixed each directly to the body of its respective bracket instead of to an arched arm projecting from the body of the bracket as heretofore, but each also projects through a slot in the bridge which is paral lel with the adjacent slot b so that when bolts h are loosened and the brackets adjusted the abutments can move freely in their slots with the brackets. An ad ditional advantage to this construction is that when lug g strikes either abutment the shock which tends to swing the bracket on its bolt h is not borne so much by the bracket and its bolt h but mostly by the side of the abutment slot h and therefore the shock does not tend as heretofore to disturb the adjustment of the bracket H or of the abutment itself. In other words, the abutment h not only cooperates with lug 9 but also assists in holding the brackets in place against the shocks to which they are subjected and the abutments themselves are therefore more rigid than heretofore. Moreover the abutments being fixed to the brackets, the relationship between each abutment and the axis of its sprocket is not disturbed when the brackets are adjusted. These advantages I have found from practical experience to be of mechanical and structural importance, but of course While I much prefer to have the abutment perform the double function of a bracket support and abutment and while this in practice is an important advantage, yet I do not mean to say that it is essen-' tial to my invention.

In the best form of my invention the brackets H are made each with a slot h opposite to and parallel with the slots 72 in the bridge and the abutments project through these slots h and are clamped therein by nuts h This construction is provided because slivers of one sizerequire one relationship between the abutments and the axes of their sprockets while with slivers of another size a slightly different relationship is required and thus by connecting each abutment with its bracket, it can be adjusted relatively to its sprocket as may be required. This capacity for adjustment can, however, be secured in other ways as for example, by making each bracket with a lug h (Fig. 4) projecting through its slot h and carrying at its outer end an adjustable screw it for engaging the lug y I do not claim broadly means for adjusting the sprocket-supporting bracket without altering the adjustment of the stop relatively thereto, nor an adjustable bracket with a stop or abutment adjustably fixed thereto, in combination with the bridge, since my said Patent No. 701,487 shows parts which in their functions and cooperative relationship are the same in these respects as the similar parts described hereinabove, but

What I do claim and desire to secure by Letters Patent is:

1. In a feed mechanism for carding machines, in combination, a carrier-supporting bridge made with a pair of longitudinal parallel slots; a bracket for supporting the sprocket or the like of the carrier-reciprocating devices, said bracket being provided with a rigid abutment projecting through one of the slots into the path of the carrier, and a bolt in the other slot for clamping the bracket to the 'bridge' 2. In a feed mechanism for carding machines, in combination, a carrier-supporting bridge made with a pair of longitudinal parallel slots; a bracket for supporting the sprocket or the like of the carrier-reciprocating devices, said bracket being made with a slot opposite to and parallel with one of the slots of the bridge; an abutment adjustably fixed in the slot of the bracket and projecting through the adjacent slot of the bridge into the path of the carrier, and a bolt in the other slot of the bridge for clamping the bracket to the bridge.

3. In a feed mechanism for carding machines, in combination, a carrier-supporting bridge made with a longitudinal slot; a bracket for supporting the sprocket or the like of the carrier-reciprocating devices, said bracket being provided with an abutment projecting through the slot into the path of the carrier, and means for holding the bracket rigid with reference to the bridge.

4. In a feed mechanism for carding machines, in combination, a carrier-supporting bridge made with a longitudinal slot; a bracket for supporting the sprocket or the like of the carrier-reciprocating devices, said bracket being provided with an abutment adjustably mounted upon the bracket and projecting through the slot into the path of the carrier, and means for holding the bracket rigid with reference to the bridge.

5. In a feed mechanism for carding machines, in combination a carrier-supporting bridge made with a longitudinal slot; a bracket for supporting the sprocket or the like of the carrierreciprocating devices, said bracket being provided with an abutment projecting through the slot into the path of the carrier, and means for holding the bracket rigid with reference to the bridge, with provision for adjusting the same longitudinally with reference to the bridge.

6. In a feed mechanism for carding machines, in combination, a carrier-supporting bridge, made with a pair of longitudinal parallel slots; a bracket for supporting the sprocket or the like of the carrier-reciprocating devices; an abutment adjustably fixed to said bracket and project ing through one of the slots of the bridge into the path of the carrier, and a bolt in the other slot of the bridge for clamping the bracket to the bridge.

7. The combination of the frame, stands adjustable thereon, the driving-wheels or rolls, supported on said stands, the drivingband or chain supported on said rolls, the carrier or traveler, driven by said band or chain, the rack supported on said frame, the pivoted plate, feed or delivery-rolls carried by said plate, gears rotary with said teed-rolls and adapted to engage said rack, one at a time,
